The objective of the research was to acquire information about the sub-surface situation in the area of the castle core and its outer ward. Geophysical methods employed included magnetometry and geoelectrical resistivity measurements. Stone debris revealed in the castle core prevented the use of methods that were to detect possible constructions, due to their limited depth reach. No structures that could be clearly interpreted were identified in the outer ward. However, the research has indicated new interpretations of a terrain depression in the south section of the outer ward, vital for the determination of the total extent of the castle complex.
